ks.exp.test: Kolmogorov-Smirnov test for exponentiality

Description Usage Arguments Details Value Author(s) References Examples

Description

Performs Kolmogorov-Smirnov test for the composite hypothesis of exponentiality, see e.g. Henze and Meintanis (2005, Sec. 2.1).

Usage

 1 ks.exp.test(x, nrepl=2000) 

Arguments

 x a numeric vector of data values.
 nrepl the number of replications in Monte Carlo simulation.

Details

The Kolmogorov-Smirnov test for exponentiality is based on the following statistic:

KS_n =\sup_{x≥q0}|F_n(x)-(1-\exp(-x))|,

where F_n is the empirical distribution function of the scaled data Y_j=X_j/\overline{X}. The p-value is computed by Monte Carlo simulation.

Value

A list with class "htest" containing the following components:

 statistic the value of the Kolmogorov-Smirnov statistic. p.value  the p-value for the test. method the character string "Kolmogorov-Smirnov test for exponentiality". data.name a character string giving the name(s) of the data.
